As prez said use the search function. Personally it doesnt matter to me if you do but to some people on the forum it does. This will keep from posting questions that have been answered already. You can find the search buttion on the right side of your page. Only down side to that is it can sometimes bring up a lot of threads.

Use the Wii FAQ link that Prez gave you. You will find it very helpfull and could answer some of your questions.

Try posting in threads already made just to get the feel of the forum.
